If I Raise Too Many Dragons, It Won't Affect My Farming!

Merlin traveled to a world with dragons and magic, and unexpectedly inherited Dragon Island and became its lord. I thought my life goal would be accomplished in one fell swoop, but I didn't expect Dragon Island to be an undeveloped island trapped in a sea of ​​mist. What's even more outrageous is that everyone is a fearful dragon, and its ability is actually related to the growth of mineral plants and magic gems? Therefore, in order to save the people (maids) on the Misty Island (all over the world), Merlin decided to carry out farming to the end, liberate productivity, and cross the Sea of ​​Mist to conquer many worlds! Many years later, Merlin lamented: "What kind of industrial revolution is there in other worlds? Dragons are the primary productive force in the magical world!" … This is the story of a time traveler who takes a book and learns magic while collecting dragons to farm and explore the world of planes.
